Haematochezia found to be most accurate symptom of bowel cancer - 99.4% specificity
Haematochezia found to be most accurate symptom of bowel cancer - 99.4% specificity
Bowel cancer is one of the most common types of cancer diagnosed in the UK. Like all forms of cancer, the prognosis significantly improves the earlier it's detected. That makes symptom awareness front and centre. A study published in the journal BMC Primary Care sought to determine which symptoms provide the most accurate predictor of bowel cancer.
For the study, 511 cases of cancer were recorded prospectively among 61,802 patients 16 years and older in Norway, Denmark, Sweden, Netherlands, Belgium and Scotland.
Bowel cancer, also known as colorectal cancer, is one of the main types of cancer associated with abdominal symptoms; hence, an in-depth subgroup analysis of the 94 colorectal cancers was carried out in order to study variation in symptom presentation among cancers in different anatomical locations.
Data was collected via a standardised form containing closed questions about symptoms recorded during the consultation.
Follow-up data were provided by the GP after diagnosis, based on medical record data made after the consultation.
GPs also provided free text comments about the diagnostic procedure for individual patients.
What did the researchers find out?
Almost all symptoms recorded could indicate colorectal cancer.
"Rectal bleeding", also known as haematochezia, had a specificity of 99.4 percent, making it the most reliable indicator of bowel cancer.
Blood in stools may also indicate gastrointestinal bleeding. When these symptoms and signs were combined, sensitivity reached 57.5 percent.
General signs to spot
The symptoms of bowel cancer can be subtle and do not necessarily make you feel ill.
According to the NHS, More than 90 percent of people with bowel cancer have one of the following combinations of symptoms:
- A persistent change in bowel habit - pooing more often, with looser, runnier poos and sometimes tummy (abdominal) pain
- Blood in the poo without other symptoms of piles (haemorrhoids) - this makes it unlikely the cause is haemorrhoids
- Abdominal pain, discomfort or bloating always brought on by eating - sometimes resulting in a reduction in the amount of food eaten and weight loss.
"See a GP if you have any of the symptoms of bowel cancer for three weeks or more," advises the health body.
Are you at risk?
The exact cause of bowel cancer is unknown. However, research has shown several factors may make you more likely to develop it.
Your risk of developing bowel (colon and rectal) cancer depends on many things including age, genetics and lifestyle factors.
Many studies have shown that eating lots of red and processed meat increases the risk of bowel cancer.
It is estimated that around 13 out of 100 bowel cancer cases (around 13 percent) in the UK are linked to eating these meats.
Processed meat is any meat that has been treated to preserve it and/or add flavour - for example, bacon, salami, sausages, canned meat or chicken nuggets.
Obesity is also a cause of bowel cancer, warns Cancer Research UK.
It is estimated that 11 out of 100 bowel cancers (11 percent) in the UK are linked to being overweight or obese.

Obesity means being very overweight with a body mass index (BMI) of 30 or higher.
BMI is a measure of whether you're a healthy weight for your height.
Lychee: Expert opinions and healthy portions
Lychee: Expert opinions and healthy portions
Quantity recommendation by Faith Seke
- Eating atleast two cups of lychee per day is highly recommended. One cup full of lychees equates to about 190 grams of the fruit. Before consuming lychees one should take into consideration their health conditions.
Quantity recommendation by Leticia Soares
- The recommended daily serving of lychee is around three to four fruits. Larger amounts than those recommended can lower your blood sugar and cause symptoms of hypoglycemia such as dizziness, confusion and even seizures in extreme cases. The ideal is to consume this fruit after meals and it should be avoided in the morning.
Quantity recommendation by Cagla E. Kayma
- Daily fruit intake. It's recommended that you get at least 1.5 to 2.5 cups of fruit a day and 2 to 4 cups of vegetables. Eating more fruits instead of dessert may help you stick to a weight control plan.
Consuming two tablespoons of honey improves blood sugar and cholesterol levels, study finds
Consuming two tablespoons of honey improves blood sugar and cholesterol levels, study finds
Consuming two tablespoons of honey can help balance blood sugar and improve cholesterol levels, according to a new study.
Experts said replacing added sweeteners in the diet – such as sugar in tea – with honey can lower the risks of illnesses associated with eating too much sugar, like type 2 diabetes, heart disease and non-alcoholic fatty liver disease.
Researchers at the University of Toronto analysed the results of 18 trials including more than 1,100 participants and found that raw honey from a single floral source had the most positive effect on the body.
They found it lowered fasting blood glucose and the number of low-density lipoprotein (or “bad cholesterol”) in the blood.
Consuming honey also increased high-density lipoproteins (“good” cholesterol”) and showed signs of improving inflammation.
All participants in the study followed a generally healthy diet, and sugar accounted for 10 per cent or less of their daily caloric intakes.
The study found that honey from a single floral source “consistently produced either neutral or beneficial effects” on the body.
Participants were given an average of 40 grams, or about two tablespoons of honey daily over the course of eight weeks.
Most of the benefits were observed in people who consumed raw honey, from False Acacia or Black Locust trees.
However, honey lost many of its health benefits after it was heated above 65 degrees Celsius.
Tauseef Khan, a senior researcher at the University’s Faculty of Medicine, said the results were surprising because honey “is about 80 per cent sugar”.
“But honey is also a complex composition of common and rare sugars, proteins, organic acids and other bioactive compounds that very likely have health benefits,” Khan said.
Experts said the results showed that not all sugars should be treated the same by health and nutrition officials.
“We’re not saying you should start having honey if you currently avoid sugar,” Khan said. “The takeaway is more about replacement – if you’re using table sugar, syrup or another sweetener, switching those sugars for honey might lower cardiometabolic risks.”
